Digimon Story Time Stranger was previously rated Steam Deck Playable but ahead of release this has been improved and it's now Steam Deck Verified.
Valve put it back through testing, and it appears the developer has solved the issue of it sometimes showing the wrong keybinds which was the only thing they noted as preventing it being Verified. Great news, as this one is sure to be a popular choice.
The compatibility notice still mentions it needs an internet connection for the first-time setup, plus it also has Denuvo Anti-Tamper listed on the Steam page.
